The industry's smallest dual channel step-down regulator can reduce the number of components and circuit board space in portable systems

analog devices, Inc. (). It is the world's leading provider of high-performance signal processing solutions that cause rapid and significant losses in physical, mechanical and optical properties. It recently launched the industry's smallest high-performance, dual channel 600mA step-down regulator adp5022 (), Designed for portable electronic systems with limited space. The size of this product is only 2mm x 2mm x 0.6mm, which is only half the size of competitive devices of the same kind. In addition, the built-in 150m a-chip LDO (low voltage differential regulator) is added to facilitate the power supply of auxiliary power rail. This high level of integration and small package can realize ultra small power management unit with high cost performance, which is especially suitable for portable instruments, smart meters, smart meters and other devices that require thin package and are sensitive to power consumption. The combination of small size, low noise architecture and high switching frequency also makes adp5022 an ideal choice for power supply of sensitive analog circuits, such as high-resolution ADC (analog-to-digital converter)

adp5022 has a built-in 3MHz voltage regulator, which provides fixed voltage output and internal compensation. Achieve excellent efficiency and performance while minimizing the size of the external filter and saving up to 12 discrete components for the system board design. In order to maintain high efficiency under light load or high load, adp5022 can automatically switch between PWM (pulse width modulation) mode and PSM (energy saving mode), and the mode pin can be used to force devices including spray and detergent into PWM mode under any load

adp5022 has some important features that can help achieve efficient noise sensitive simulation and RF system design. The key to design sensitive analog circuit is to make the voltage regulator physically close to the load. The compact adp5022 allows the system designer to place the power regulation circuit right next to the load point, thereby minimizing PCB parasitic effects. This step-down regulator adopts low-noise driver technology, with high switching speed and phase staggering clock, which can further reduce noise. These features, together with the integrated high PSRR LDO, provide an ideal solution for powering high-performance analog and digital loads such as high-speed, high-resolution data converters

adp5022's key performance and advantages

-- small 2mm x 2mm, 16 pin WLCSP package
